This page explains how to set automated notifications to alert you when inventory has fallen below a previously specified threshold.
Replenishment Alerts enable you to manage your inventory in Amazon's fulfilment centres without needing to constantly monitor each listing. You can set the alert quantity for individual products or groups of products. When the listing's fulfilable quantity reaches your threshold, either in units or weeks-of-cover (the number of weeks of on-hand fulfilable inventory based on your sales over the last 30 days), we notify you by sending you a Replenishment Alert email.
When you select an alert quantity for a given product, select a quantity based on your average sales and the time it takes to order and ship stock to a fulfilment centre. For example, if it takes you two weeks to order and ship a product and you sell about 100 units of that product in a week, it would be advisable to set the alert quantity to at least 300 units. When your fulfilable inventory for that product reaches 300 units in our fulfilment centres, we will notify you. This will give you three weeks to place an order with your vendors and send in a shipment to our fulfilment centre before your inventory is depleted.
Alternately, when you a select a weeks-of-cover threshold, you should select the number of weeks that it takes you to order and ship stock for that product to Amazon fulfilment centres.
To configure Replenishment Alerts:
You can identify listings with Replenishment Alerts from the Inventory Amazon Fulfils page. A gold bell will appear in the Fulfilable column next to the quantity. If the inventory has reached the replenishment alert quantity, the bell will turn red.
